Does anyone know how the vacuum table works I attempted to make it a few months ago but it did not have enough suction.
Any Ideas?

Haven’t tried one yet - that’s next 😆Does anyone know how the vacuum table works I attempted to make it a few months ago but it did not have enough suction.

If it has a Z axis you won’t need the servo for cutting heightI need to convert my cheap 300x300 5W laser cutter into one of these.
WHAT TO DO?:
a) Longer rails
b) extend harness to match longer rails
c) build reciprecating needle head to replace laser
d) make a servo mount for the cutting head to replace laser intensity with cutting height
....
No native Z. I was going to use the laser intensity for the z-axis. It is PWM. Only question is what type of pwm, and is it directly compatible with a servo.If it has a Z axis you won’t need the servo for cutting height
Here are the files. The tensioners are hacked from X Axis Tensioner for TimSav DIY CNC Needle Cutter by dehager on Thingiverse: https://www.thingiverse.com/thing:4034051. You'll need to down load that to get the internal parts for the tensioners. I'll be uploading to Thingiverse soon.Could you post the files that you used I would like to do that to mine.
Looks great by the way!
Why would you not just keep the laser? You can cut faster with that and it would be quieterI need to convert my cheap 300x300 5W laser cutter into one of these.

How many of each part do I need? Could you take some more pictures of yours.Here are the files.

Because a 5W laser is not a great option for cutting foamboard. Nothing would stop me from using BOTH the laser and the needle cutter if I do it correctly. Just swap the tool out.Why would you not just keep the laser? You can cut faster with that and it would be quieter
make sure that your board is running GRBL first. It it is, I would flash it with GRBL 1.1h_servo as it is already setup for pwm for a servo. Your laser may require up to 5000hz while a servo uses 50 hz. Some lasers will also use a wider range of pwm frequency and work fine with the 50hz. GRBL-1.1h-servoNo native Z. I was going to use the laser intensity for the z-axis. It is PWM. Only question is what type of pwm, and is it directly compatible with a servo.
You are correct, a led laser will only burn the top paper and will not touch the white foam core. If you are cutting black foam board with the black core it will cut. If you want to switch back and forth then GRBL 1.1h-servo is the way to do it as the older servo version used with the timsav does not have the M4 laser mode. I did a quick video on installing it on a uno/cnc shield hereBecause a 5W laser is not a great option for cutting foamboard.

Ok that makes senseBecause a 5W laser is not a great option for cutting foamboard. Nothing would stop me from using BOTH the laser and the needle cutter if I do it correctly. Just swap the tool out.
You need 6 wheel spacers and 1 of everything else. I made mine black so the pictures aren't very helpful but here's a video showing how it assembles (I guess in the video it shows it disassembling ).How many of each part do I need? Could you take some more pictures of yours.
And for other hardware I just need an assortment of screws, another stepper motor, and the aluminum extrusion.
Thank you!

Wow very impressive video!You need 6 wheel spacers and 1 of everything else. I made mine black so the pictures aren't very helpful but here's a video showing how it assembles (I guess in the video it shows it disassembling ).
It takes:
3 V wheels and 3 M5x40 bolts & nuts
2 T nuts and bolts to hold the tensioners to the rails
1 M5x10 to hold the motor mount to the rail
4 bolts to hold the motor to the mount
2 idler pulleys same as ERC original
1 drive pulley same as ERC original
about 2 meters of belt
1 meter of 20x20 V extrusion
A can of spray paint can accomplish essentially the same thing in a lot less time than reprinting everything.Wow very impressive video!
I will start buying parts for this soon.
I most likely will go threw the whole machine and just reprint every thing, because right now it is green, blue, light blue, white, black, etc
So it looks unprofessional lol because it is
I really like the animations fusion 360 lets you do. To me it's way clearer than pictures and instructions.Wow very impressive video!

Yes but the 3d printed parts were made before my new 3d printer so they are very poor qualityA can of spray paint can accomplish essentially the same thing in a lot less time than reprinting everything.
I use onshape to design my parts I think it can do that to but I would have to pay for it then.I really like the animations fusion 360 lets you do. To me it's way clearer than pictures and instructions.
